    # Fields to convert to/from BigDecimal.

    # Constructs an AIM transaction. You can use the new AIM transaction object

    # to issue a request to the payment gateway and parse the response into a new

    # AuthorizeNet::AIM::Response object.

    #

    # +api_login_id+:: Your API login ID, as a string.

    # +api_transaction_key+:: Your API transaction key, as a string.

    # +options+:: A hash of options. See below for values.

    #

    # Options

    # +transaction_type+:: The type of transaction to perform. Defaults to AuthorizeNet::Type::AUTHORIZE_AND_CAPTURE. This value is only used if run is called directly.

    # +gateway+:: The gateway to submit the transaction to. Can be a URL string, an AuthorizeNet::AIM::Transaction::Gateway constant, or one of the convenience symbols :sandbox, :test, :card_present_test, :card_present_live, :card_present_sandbox, :card_present_production, :production, or :live (:test is an alias for :sandbox, :card_present_test is an alias for :card_present_sandbox, :card_present_production is an alias for :card_present_live, and :live is an alias for :production).

    # +test+:: A boolean indicating if the transaction should be run in test mode or not (defaults to false).

    # +allow_split+:: A boolean indicating if split transactions should be allowed (defaults to false).

    # +delimiter+:: A single character (as a string) that will be used to delimit the response from the gateway. Defaults to ','.

    # +encapsulation_character+:: A single character (as a string) that will be used to encapsulate each field in the response from the gateway. Defaults to nil.

    # +verify_ssl+:: A boolean indicating if the SSL certificate of the +gateway+ should be verified. Defaults to true.

    # +device_type+:: A constant from DeviceType indicating the type of POS device used in a card present transaction. Defaults to DeviceType::UNKNOWN.

    # +market_type+:: A constant from MarketType indicating your industry. Used for card present transactions. Defaults to MarketType::RETAIL.
